Study design: Observational Model: Cohort, Time Perspective: Prospective

Primary outcome: the efficacy of the methadone maintenance treatment in addicted heroin patients, evaluating the correlation among efficacy and adequate dosage in comparison to not adequate dosage.

Secondary outcome:

QT prolongation risk in patients addicted to heroin who have undertaken MMT

psychopathological status of observed patients in correlation with the adequate dosage in comparison to not adequate dosages

pharmacoeconomic condition correlated with the adequate dosage in comparison to not adequate dosage.

Detailed description: 500 patients will be selected among all patients addicted to heroin according to DSM-IV_TR (Diagnostic and Statistical Manual of Mental Disorders IV_ text revision), in maintenance methadone treatment, observed in the involved sites.
